Ruleta de la Muerte (2012) (Spanish for "Roulette of death") was an annual professional wrestling major event produced and scripted by the Mexican professional wrestling promotion International Wrestling Revolution Group (IWRG), which took place on September 6, 2012 in Arena Naucalpan, Naucalpan, State of Mexico, Mexico. The focal point of the event was the eponymous Ruleta de la Muerte eight-man tournament where all participants put their wrestling mask or hair on the line. The Ruleta de la Muerte tournament is a Lucha libre stable, a tournament which unlike traditional tournaments it is the loser that advances in the tournament, advancing to the final that is contested under Luchas de Apuestas or bet rules.
